Linear launches 1A DC/DC regulator system
A Linear Technology product story
Edited by the Electronicstalk editorial team Feb 8, 2010
Linear Technology has introduced a complete 1A DC/DC regulator system in a package.
The LTM8031 is the second member of the company's electromagnetic-compatible (EMC) DC/DC Umodule range.
Linear Technology has introduced a complete 1A DC/DC regulator system-in-a-package, the LTM8031.
The system includes an inductor, a switching DC/DC controller, power switches, filters and all support components housed in a 9 x 15 x 2.82mm land-grid-array (LGA) package.
The LTM8031 has been tested by an independent electromagnetic-interference (EMI) laboratory and is compliant with the radiated-emissions requirements of EN55022 Class B.
The switching frequency can be adjusted from 200kHz to 2.4MHz with a resistor or synchronised to an external clock.
The device operates from a wide input voltage range of 3.6V to 36V and regulates an output voltage from 0.8V to 10V at up to 1A.
Applications for the LTM8031 include converting and regulating automotive battery voltage, distributed power supply and high-voltage industrial and avionics systems.
The LTM8031 weighs 1.2g and is offered in industrial and military temperature-grade specifications.
For a higher output current up to 2A, the LTM8032 is available with identical layout and pin functions.
To improve efficiency at light loads, the device automatically activates Burst Mode operation, which keeps the output capacitor charged to the proper voltage with single cycle bursts of current followed by sleep periods, minimising input quiescent current.
The LTM8031 is priced at USD9.95 (GBP6.28) in 1,000-piece quantities.
